4: Claims. (Cl. 51-105) adapted for removing the ridges in the cylinders of an internal combustion engine.

A primary object of this invention is the pro-l vision of an improved ridge remover adapted to remove the ridges formed, or worn in the interior walls of the cylinders, without affecting the accuracy of the internal alignment and diameter of the cylinder.

A further object is the provision of such a device which will remove such ridges, provided with a control means, whereby cutting into the Walls of the cylinder is precluded. I

An additional object is the provision of such a device adapted to be particularly effective in retively unskilled workman.

Still other objects reside in the combinations of elements, features of construction, and arrangements of parts, all as will be more fully pointed out hereinafter and shown in the accompanying drawings, wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a side sectional View of one form of device embodying the instant invention, shown in association with a cylinder upon which it is to be used.

Figure 2 is a top plan view of the device of Figure 1.

, Figure 3 is a sectional view taken substantially along the line 3-3 of Figure 1, certain parts thereof being indicated in dotted lines.

Figure 4 is an enlarged fragmentary bottom plan view of a certain constructional detail.

Figure 5 is an enlarged side elevational view of certain additional constructional details, and

Figure 6 is an enlarged perspective view of still further constructional details.

Like reference `numerals refer to like parts throughout the several views of the drawings.

Having reference now to the drawings and more particularly to Figure 1, there is generally indicated at I0 a body block suitably supported as on legs II and having a bore or aperture I2 passed vertically therethrough. Bore I2 has extending therethrough and mounted therein for rockingmovement, a drive shaft assembly I3 containing a drive shaft I3', on the lower extremity of which is mounted a :pulley I4 adapted to accommodate a V-belt or the like having driving connection with any desired source of power (not shown) to rotate the shaft I3'.

to a piston ring ridge remover and more particularly to such a device The mounting means for shaft assembly I3 takes the form, as best shown in Figure 6, of a block I5 having a vertical bore I6 extending therethrough into which the shaft assembly I3 is fitted, said block I5 being pivotally secured, as by pivots I1, to a, U-shaped yoke I8 which is mounted to slide in a bore 3| which extends through one side of the body II) along an axis perpendicular to the axis of the bore I2. Sleeves I8a surround shaft assembly I3 above and below block I5 and have secured thereto ball headed studs |90. which engage in suitable sockets in blocks I9b which are slidable in vertically spaced horizontal passages 20 formed within block I0. Abutting the inner end of each block lsb is a compression spring 2|, the outer end of each of which engages a shiftable stop 22 positioned for movement with a recess 23 which opens into vthe passages 20 and through the opposite side of the block I0. A screw 25 extends through and engages the threads of a suitable threaded opening 21 in a closure member 28 which closes the end of the recess remote from the passages 20. The inner end; of the screw 25 is secured to stop 22 and the outer end of said screw carries an operating handle 26. Closure 28 is adapted to be secured to block I Il as. by means of screws 3U or the like passed through a suitable flange formed on closure member 2B- and engaging in suitable threaded recesses in the block. The bore 3l is disposed in the side of the body block opposite the openings 20 and contains a spring 32. The end of bore 3| remote from the bore I2 is closed by a threaded plug 33 which forms a stop engaged by one end of a. spring 32, the opposite end of which bears on the yoke lu and cooperates therewith in forming a spring loaded neutralizer to oppose the pressure exerted by springs 2| on the shaftassembly I3. From the foregoing, it will be seen that the shaft assembly I3 is mounted within bore I2 for relative pivotal motion, and may be biased toward and away from the cylinder walls, to be described hereinafter, by means of rotation of handle 26 changing the relative position of member 22 and hencethe pressure exerted by springs 2 I.

Mounted for rotation in a suitable recess 40 in the upper portion of block III is a work supporting carriage generally indicated at 4I comprising an annulus 42 provided on its lower face with teeth 43. A depending annular flange 44 is carried at the inner edge o-f the annulus and enters the recess 40. The annulus 42 is mounted on a suitable ball race 45 to permit free rotation thereof, such rotation being effected by means of a pinion gear 46 driven through a shaft 47, from any suitable source of power (not shown), and engaging teeth 43 of annulus 42.

Mounted on the upper surface of annulus 42 is an adapter ring 50 which may be of any suitable "J the foregoing,

thickness, or diameter to accommodate varying types and sizes of cylinders This adapter 50 may be secured to the carriage 4I by bolts 52 or the like WhichY may ,also be...used to secure the work 5l to the carriage 4 l. The upper end of drive shaft I3 has secured thereto, as by screws' 56.' a

disk 55 of any suitable abrasive material. Disk- 55 is adapted for the removal of the ridges Within scribed hereinafter x I A A s best shown in Figure `5, an indicatinglldevice comprised of a housing Bil'is secured, as by a ring 6l, to the drive shaft assembly leradjacentthe disk 55 and secured Within the housing Ell is a contact button 62 which is positioned beneath and adjacent abrasive Wheel 55. .button 62 is connected by a suitable conductor 63' This contact to a suitable indicator light E4 mounted in a bracket 65 secured to any suitable portieri of block I0.

"The operation of the device should now, from be readily understandable. i An abrasivendiskv55, of thedesired diameter ,and

, thickness is, positioned on theA :upper end of` the i driveshaftll" of' the shaft assemblyA I3; and'c'on-- tact button 62 is adjusted as by means' of 'con- 1 tact set screw 63 to extend th'e desired distance outwardly with respect to housing iilLHsuch` distance being substantially identical to the radius of the abrasive Wheel 55; A suitable adapter 5D is Athen placed in `position on annulusl 42 and the cylinder 5i secured in position thereon. Screw 25 is' adjusted by' means of handle 26 until shaft I3 I; has moved abrasive wheel 55 into'contact with the fridgeil (see Figurell' of'thecylinder tobe removed. 'Ihe drive shaft I3' is then-v rotated at la desired .speed rotating the' abrasive Wheel155.

' Simultaneously, the annulus42' is driven byY pinlion 43 to rotate the cylinder uniformlyexposing .all portions of the ridge successively to the abra- "sivewheel 55; It will be seen that those portions of the cylinder Wall on which a ridge has not been formed will not be affected by the abrasivewheel 1 55 since stop or contact `62 by'its vabutment with the Wall of the cylinder prevents the grinding Wheel from vundercutting the same. Simultane# ously a circuit is closed illuminating indicator .'light 64. Thus,.when ,the ridge has-been completely removed, contactl 62,'wil1 cause light 64 to ,remain illuminated through an'entire revolution ofthe cylinder to indicate the completion of such removal;wherupon the operation of the-machine may be discontinued.

From the foregoing it will now be'seerr that "there 'is herein provided a device accomplishing all the objects of this invention and others including many advantages of great practical utility and commercial importance.

As many embodiments may be madek of this inventiveconcept, and as many modications may be made in the embodimentlierein shown-"and described, it is to be understood that all ,matter hereinbefore isto be'interpreted merely as-llus- .trative and not in a limiting sense.
